► Fig.12: 1. Impact socket 2. Hole 3. Square drive
4. Detent pin
Align the hole in the side of the impact socket with the
detent pin on the square drive and push the impact
socket onto the square drive until it locks into place. Tap
it lightly if required.
To remove the impact socket, simply pull it off. If it is
hard to remove, depress the detent pin while pulling the
impact socket.
Installing hook
WARNING:
Use the hanging/mounting parts
for their intended purposes only, e.g., hanging the
tool on a tool belt between jobs or work intervals.
WARNING:
Be careful not to overload the
hook as too much force or irregular overburden
may cause damages to the tool resulting in per-
sonal injury.
CAUTION:
When installing the hook, always
secure it with the screw firmly. If not, the hook
may come off from the tool and result in the personal
injury.
CAUTION:
Make sure to hang the tool
securely before releasing your hold. Insufficient
or unbalanced hooking may cause falling off and you
may be injured.
► Fig.13: 1. Groove 2. Hook 3. Screw
The hook is convenient for temporarily hanging the tool.
This can be installed on either side of the tool. To install
the hook, insert it into a groove in the tool housing on
either side and then secure it with a screw. To remove,
loosen the screw and then take it out.
Using hole
WARNING:
Never use the hanging hole for
unintended purpose, for instance, tethering the
tool at high location. Bearing stress in a heavily
loaded hole may cause damages to the hole, result-
ing in injuries to you or people around or below you.
► Fig.14: 1. Hanging hole
Use the hanging hole at the bottom rear of the tool to
hang the tool on a wall using a hanging cord or similar
strings.
OPERATION
CAUTION:
Always insert the battery cartridge
all the way until it locks in place. If you can see the
red indicator on the upper side of the button, it is not
locked completely. Insert it fully until the red indicator
cannot be seen. If not, it may accidentally fall out of
the tool, causing injury to you or someone around
you.
► Fig.15
Hold the tool firmly and place the impact socket over
the bolt or nut. Turn the tool on and fasten for the proper
fastening time.
The proper fastening torque may differ depending upon
the kind or size of the bolt, the material of the workpiece
to be fastened, etc. The relation between fastening
torque and fastening time is shown in the figures.
